MACHINE FOR FINISHING GLSSWARE.

SPECIFICATION forming part of Letters Patent No. 648,272, dated April24, 1900.

Application filed August 26 1899. Serial No. 728,623. (No model.)` i

To @ZZ whom it may concern,.-

Be it known that I, CHARLES LENG, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have inventednew and useful Improvements in Machines forFinishing Glassware, of which the following is a specification.

This invention is a machine for finishing the necks of bottles and otherglass articles, and relates more particularly to certain improvementsover the machines patented to myself and C. F. Leng Marc h 18, 1890, No.423,482, land to myself May 20, 1890, No.. 428,214. In the patentedmachines just re ferred to two shafts, one Within the other, rotate inopposite directions, one carrying 4a former for the interior of thebottle-neck and the other carrying dies for forming the neck exterior.The range of said machines is limited, as the inner and outer formers ordies are not adjustable longitudinally with relation to each other, andsuch adjustment is one of the improvements embodied in my presentinvention. A

Further improvements are in the manner of supporting and 'adjusting theouter dies and in the means for throwing the machine in and Theinvention also includes improved means for grooving the interior of thebottleneck.

Other advantages and improvements will `become apparent as the nature ofthe invention is developed by the following speciiication, the claimsappended thereto, and bythe accompanying drawings, in Which-- Figure 1is a side elevation of my'improved machine, portions thereof beingbroken away and other portions shown in section. Fig. 2 is alongitudinal sectional view taken at right angles to the neck-formingmechanism shown in Fig. 1. Figs. 3 and 4 arecross-sectional views onlines 3 3 and 4 4, respectively, of Fig. 2. Figs. 5 and G arelongitudinal sectional views, taken at right angles to each other, of anadaptation ofthe machine for forming an interiorgroove in thebottle-neck. Fig. 7 is a cross-sectional view on line 7 7 of Fig. 5.Fig. 8 is a face view of the formingmachine shown in'Figs. 1 and 2, thebase be- 5o ing shown -in section. Fig. 9 is asectional view on line 9 9of 1.

l. is a base supported on legs 2, and resting on the base is bed-frame 3of the machine, from which Arise bearing-posts 5,and jour- 55 naled inthese posts are shafts 6 and 7, o'ne within the other, and carrying,respectively, pulleys 6 and 7 for driving the machine'. Shaft 6 isthreaded at the inner end, and shaft 7, extending through shaft 6, isslotted at its 6o innerd end at 8.

Uniting with the threaded en d of shaft 6 is chuck-head 9, depressedlongitudinally on opposite sides of its exterior at 9', and pivoted at10 in these depressions are arms 11, which 65 at one end areoutwardiydeiiected at 12 to operatively engage cone-collar 13, slidableon chuck 9. The opposite ends of said arms eX- tend 'beyond thecorresponding end of th'e chuck and carry dies 14. The latter arepiv.-7o oted between their ends at 14' to said arms, and the desired=angle atwhich the dies work is secured and maintained by setrs'crews 15, workingthrough the arms and, locked by nuts 15'. The inner faces of .the diesare shaped 75 to give the bottle-neck exterior the requisite form, whichmay be changed and varied as vdesired by substituting diderent dies.

Fitting the bore of chuck 9 is bushing 16, adjustable longitudinally andheld by set- 89 screw 17. l

18 is a short shaft rotatable in the bushing and peripherally grooved at18' to receive pin 19, which holds it against longitudinal play. Oneextremity of the shaft is attened at 2O 85 to enter slot 8 of shaft 7,andV the shaft is flanged at 21 to fit a corresponding depression in theend of bushing 16, and beyond the flange is integral inner die or'forming plug 22, which enters the bottle-neck and shapes 9o theinterior thereof, said plug being flattened on opposite sides to permitegress of air from the bottle during the forming operation.

'Integral with the extremity of bushing 16 is transverse plate 23, thesides of which are 95 almost intersected by flange 21, withwhich saidplate alines, and said sideso'f the plate are also substantiallycoincident with the inner ends of dies 14. The plate has greater lengththan width, and hcncehas considervableprojection at right angles todies1 4, as

shown in Fig. 4. Y .Y v f Slidableon bedframe 3 is carriage 24, and;vertically adjustable in the-'upright members; of the carriage are racks26, having Vshaped notches to receive handle 27 of bottle-holder 28, theracks being clamped in desired adjustment by screws 29. j

. 30 is a bellf'crank lever fulcrumed to -the carriage at 31 andadjustably cf, ,'e'cted at its lower end to reach-rod 32, whi nl.connects with stem 33' of fork 33, which embraces conevcollar '13,whereby the latter is-'moved to acf tuate arms 11. Carriage 24 maybemoved toward Aandraway, from the forming mechanism, as circumstances mayrequire, andis se-v cured in position by clamping-plate 34 and boltr34'.In operation the bottle-holder is placed in position shown in Figfl,remaining all the while in the grasp of the operator at `about points X,with die-plug 22 entered in the bottle-neck, dies 14 being held away bycentrifugal actionI until closed onto the neck by cone 13, the inner andouter dies having c onstant rapid rotation inopposite directions.

Lever 3() is -then drawn up by one hand of thev operator withoutreleasing handle 27 of the Vbottle-holder, thereby moving cone 13against the deflected ends l2 of arms 11 andclosing dies 14 on "theexterior'of the bottle-neck, as seen in' Fig.'.2. With the innerando'uter dies rotating oppositely ,the bottle remains still and itsneck is quicklylgivenits inte-` rior and exterior form. The extremity ofthe -`neck bears against revolving plate 23, which Y smooths andfinishes it, preventing fins` vor other Aroughness from remainingthereon.k Then theoperation is completed, lever 30 `is simply released,and the centrifugal ,action of dies l4-.throws them clear ofthe bottle,

and the latter is quickly withdrawn and another inserted by manipulationof thel bottleholder. y t

35 is an elevated tankhavingtwo compartments, one for oil and the otherforsalt'water, whichdrip from a common spi got"36onto` the dies, keepingthem in proper condition for finishing and polishingthe glass.

When the salme istov be used, bushing 16 and shaft 18 are Tremoved from chuck 9 andbushing 37 inserted and sej cured in proper longitudinal adjustment byset-sere w 17. Rotatable jin bushing 3'iiissghaft slotted longitudinallyat 39 and at its rear end flattened at 38 to enter slot 8 of shaft 7.Said shaft is formed at the outer end with circular head 40, having acontinuous peripheral groove to receive screws 37', entering terior asdescribed of former22.

from facing-plate 37- of bushing 37, whereby shaft 38 is held againstylongitudinal nieve- ,ment, yet is free to rotate. Facing-plate 37'corresponds to plate 2.3 of bushing 16 and perfor'msthe same work ofsmoothing the end of thebottle`neckr y .v The interior-,die orformerconsists of `two jawflike me1nbers'42, pivoted together and to rshaft'381,iu' the slot of the latter in scissors fashion, as indicated at 43.ARear ends 44 of the `jaws cross each other in diagonal lines, theextremities of the crossed parts forming four bearing-points 45, whichprotrude from shaft-slot -39 and hetweeirwhich cellar 46 is movable onshaft 38. orally grooved to receive angularfiugers 47, extending theretofrom cone 13, the fingers passing through slots 48 in chuck 9. Theoperative endsof the die or former members are pointed and narrow incross-section, and each carries a'nib or projection 50, which when theformer members are separated turn groove 51 i in the neck interiorforsealing or other purposes. Otherwise the divided-former performs thesame work'inshaping the neck inyThe former is opened and closed bythesame movement of cone 13whieh aetuates dies 14. Different forms ofgrooves, depressions, tbc., may be Ahad by providing the former memberswith projections corresponding tothe effect desi red.

Nor delrestrict kmyginvention to inner and outer dies rotating in oppositedirections, as they 'may be used 'independently of each other or in anyother desired relation.
